The WPRC40CSP is a heavy-duty IP65 EV RCBO kit equipped with a 40A C Curve Type A RCBO and a pre-fitted Type 2 Surge Protection Device (SPD). It combines overload, short circuit, AC/DC earth leakage, and transient surge protection in a single compact weatherproof enclosure.
Built for light commercial EV chargers, renewable-heavy installs, and domestic systems with high inrush currents, the WPRC40CSP ensures compliance with 18th Edition Amendment 2. Its dual-handle trip system allows installers to identify faults quickly and keep circuits safe under demanding conditions.
Installer Tip: The 40A C Curve version is best suited for commercial EV chargers or renewable systems with higher starting currents. For lower inrush loads, use the 40A B Curve variant.
Key Features
- 40A C Curve Type A RCBO – designed for high inrush loads (30mA AC + 6mA DC)
- Integrated Type 2 SPD – 20kA/40kA transient surge defence
- Dual-handle tripping – clear indication of overload vs earth leakage
- IP65 UV-resistant enclosure – fully weatherproof
- Pre-installed SPD module and earth/neutral bars
- Compliant with BS EN 61009, BS EN 61439-3, and BS 7671:2018 A2
